The nism by meansoi which abobhinfor an electrolytic cell is covered with netting which netting is retained in place by a thread. The machine to which this coating device is attachable in addition performs other operations upon the bobbin. Since this forms no part of this invention, these additional operations and the construction of the machine whereby they are performed will not be described.

The article to be coated after being brought into contact with the coating wheel 17 is rotated in order to assure that the entire circumference thereof is coated with the liquid or parafiin L. A rotating wheel 37 is carried upon a shaft 38 journalled in a bearing 39 and the roller 37 is rotated by any means such as a sprocket 40 connected with a rotating drive. The bobbin B when advanced into waxing position comes into contact with the rotating roller 37 so that the bobbin B and carbon pencil P are rotated thereby while held stationary in the coating position E. This assures that the entire periphery of the end of the carbon pencil comes into contact with the rotating coating wheel 17 and in contact throughout its periphery with the liquid carried by the wheel. The bobbin is also so positioned that the end of the carbon pencil P comes into contact with the shoulder on the coating wheel 17 so that the face or end of the carbon pencil P is also coated with the wax or liquid. Incidentally,

the rotating roller 3'7 is the roller upon the bobbin winding machine which creases the end of the netting upon the back end of the bobbin B. So far as the parafiining operation is concerned,

, however, the roller '37 provides the rotating means for the bobbin B while the bobbin is in the coating position.

The coating wheel 1'7 and the shoulder 30 carried thereby are sufficient to coat the end of the article or carbon P as well as the face of the end of the carbon. It may occur in some bobbins under the process by which they are manufactured, that for some reason the carbon pencil P does not project the normal and usual distance from the bobbin. In such case, there is some possibility that the face of the end of the carbon will not come into contact with the shoulder 30 so that one or two out of a large number of bobbins may not be sufficiently coated or waxed upon the very end. In order to avoid this possibility and to assure that every carbon is completely waxed or coated, a brush 43 is carried upon a holder 44 which is adjustably carried in a supporting means 45. The supporting means 45 is in turn adjustably carried in a bracket 46. A screw 47 looks the supporting means 45 in the bracket 46 and the screw 48 looks the brush holder in adjusted position in the supporting means. By this construction the longitudinal position of the brush 43 may be adjusted and it may also be adjusted rotatably in the supporting means 45. The brush 43 may also be adjusted by means of the adjustment between the supporting means 45 and the bracket 46 as will be apparent, so that the length of the end of the article to be coated and the angle of inclination of the brush can be adjusted at will.

The brush 43 contacts with the periphery of the larger portion or circumference 29 of the coating wheel 17. This brush wipes off the liquid or wax upon the larger diameter 29 so that an accumulation of liquid is obtained which flows down onto the carbon P and between the end of the carbon and the shoulder 30, in case the carbon should fail to contact with the shoulder. With this construction the entire end of the article or carbon will always be coated with the parafiln or liquid and a suflicient supply of liquid upon the brush is assured.

The larger circumference 29 of the wheel 17 serves as a means for raising or supplying coating liquid to the brush. The brush 43 is simply a means for accumulating the liquid upon the larger circumference 29 adjacent to the carbon pencil so that the liquid may flow down between the end of the carbon and the shoulder 30 in case the carbon fails to contact with the shoulder. The brush also assists in coating or applying the liquid to the end of the pencil as well as uniformly distributing the liquid thereupon. The brush separately is capable of coating the end of the article and the wheel 17 with its smaller circumference and the circumferential shoulder 30 is also separately able to coat the end of the article. Each part together, however, renders doubly certain that the end of the carbon pencil P will be coated with liquid and that the liquid will be uniformly distributed thereon.

The coated carbon of the bobbins may be delivered where desired so that the parafiin may harden. A jet of air may be supplied by the nozzle 50 at the subsequent position P which quickly cools on the paraifin. This may be provided if desired, although it is not essential.
